  • 摘要:

    針對現(xiàn)有虛擬化云無線接入網(wǎng)絡(luò)(C-RAN)資源利用率低、能耗高、用戶服務(wù)質(zhì)量無法得到保證等問題，該文提出一種能耗和時延感知的虛擬化資源分配機(jī)制。根據(jù)虛擬化C-RAN的網(wǎng)絡(luò)特點(diǎn)及業(yè)務(wù)流量特征，考慮資源約束和比例公平，建立能耗和時延優(yōu)化模型。進(jìn)而，利用啟發(fā)式算法為不同類型虛擬C-RAN和用戶虛擬基站分配資源，完成資源的全局優(yōu)化配置。仿真結(jié)果表明，所提資源分配機(jī)制在提高網(wǎng)絡(luò)資源利用率的同時，不但使能耗節(jié)省了62.99%，還使時延降低了32.32%。

    Abstract:

    To solve the problems of low resource utilization rate, high energy consumption and poor user service quality in the existing virtualized Cloud Radio Access Network (C-RAN), a virtual resource allocation mechanism based on energy consumption and delay is proposed. According to the network and traffic characteristics of the virtualized C-RAN, considering the resource constraints and proportional fairness, an energy consumption and delay optimization model is established. Furthermore, a heuristic algorithm is used to allocate resources for different types of virtual C-RAN and user virtual base stations to complete resource global optimization configuration. Simulation results show that the proposed resource allocation mechanism can effectively save energy by 62.99% and reduce the latency by 32.32% while improving the network resource utilization.
